Crumbl Cinnamon Cookie Recipe

This Crumbl Copycat Cinnamon Cookie features a cinnamon sugar cookie, cream cheese frosting, and a topping of Cinnamon Toast Crunch cereal. Roll these cookies in cinnamon sugar before baking, frosting, and sprinkling with sweet cinnamon toast breakfast cereal!

Crumbl cookies are all the rage right now and it’s no surprise that baking them at home is taking off too. When I saw Crumbl’s various “breakfast cereal” cookies that came out recently, I knew I had to replicate at least one. Cinnamon Cookie with Cinnamon Toast Crunch it was!

This copycat Crumbl cinnamon cookie recipe starts with a basic sugar cookie base. The additions of brown sugar and sour cream keep the cookie soft with just the slightest tang.

Scoops of cookie dough are rolled in a cinnamon-sugar mixture, flattened on a cookie sheet, and baked. The cooled cookies are frosted with a smooth and indulgent vanilla-cinnamon glaze and topped with a simple sprinkle of cinnamon toast cereal.

Crumbl Cookies don’t hold back, so these cookies are indulgent and sweet, but oh so fun! Now, if you want to just make some plain cinnamon cookies, that’s fine too. Just leave off the frosting and cereal. Easy!

Ingredients You Will Need

First we’ll mix up a simple cinnamon sugar for which you will need:

• granulated sugar
• ground cinnamon

Then, we need the ingredients for the crumbl cinnamon cookies:

• all-purpose flour (I always HIGHLY recommend weighing your flour!)
• cornstarch (keeps these cookies soft)
• baking powder
• salt (regular table salt)
• ground cinnamon
• unsalted butter, very soft
• granulated sugar
• brown sugar
• large egg
• sour cream (use the full-fat stuff!)
• vanilla extract

Finally, we’ll whip a quick cream cheese frosting and top these sweet cookies with a sprinkle of cereal:

• cream cheese (use full fat block style cream cheese, not whipped cream cheese)
• unsalted butter
• confectioners’ sugar 
• whole milk
• vanilla extract
• ground cinnamon
• Cinnamon Toast Crunch Cereal

How to Make (Copycat) Crumbl Cinnamon Cookies

Let’s walk through the recipe together!

Cinnamon Sugar

Super easy! Just mix together sugar and cinnamon and set aside. This amount of cinnamon is perfect for providing plenty of cinnamon flavor without overwhelming the cookies.

Cinnamon Cookie Dough

I skip the silicone mats and line my cookie trays with parchment paper.

Whisk together the flour, cornstarch, baking powder, salt, and cinnamon until fully combined and set aside.

Next up, cream together the very soft butter and sugars. After they are well incorporated, beat in the egg and vanilla extract. Then, add in the sour cream, mixing until just combined.

Fold the dry ingredients (flour mixture) into the wet (butter mixture) until just combined. The dough will be a little wet/sticky, but still manageable.

Divide up the dough into 16 cookies (about 50g or around 3 tablespoons each). Roll each cookie dough ball in the cinnamon sugar mixture, place on the cookie trays (eight to a large tray works well), and flatten to about 1/2″ with your fingers or a flat-bottom glass.

These cookies bake for right around 12 minutes, but keep a close on them because every oven is a little different.

Cream Cheese Frosting

Sign me up for cream cheese frosting anytime. I originally tried topping these cookies with a basic powdered sugar glaze and it was just way too sweet. The cream cheese frosting is a much better fit, but I thinned it down to keep things balanced and not overly sweet.

Soften cream cheese and butter and whip with a hand mixer. Add in the confectioners’ sugar and whip until light and fluffy, about two minutes. Next, add the vanilla extract and stir to combine, then slowly add whole milk until desired consistency is reached. Sprinkle in a pinch of cinnamon for a pretty speckled glaze.

Assemble Cookies

Don’t go overboard with the frosting/glaze. There’s just enough for 16 cookies (although you might lose a cookie or two like I did if you have eager taste-testers visit your kitchen!) and if you add too much it’ll feel too sweet.

After frosting, sprinkle with a topping of Cinnamon Toast Crunch cereal and enjoy!

How to Store the Cookies

These cinnamon cookies are great served warm or cold. If you don’t plan on eating all the cookies right away, it’s best to store the cookies unfrosted because the cereal will become soft and chewy after sitting on the frosting for a few hours.

When ready to frost and eat, just warm up the frosting for a few moments in the microwave, spread on the (mostly cool) cookies, and top with the cereal.

Alternatively, you could also store the cookies frosted and then heat up an individual cookie to slightly soften the frosting (10-30 seconds in the microwave) and add the cereal topping. Also note that the cookies can’t be stacked without marring the frosting once frosted.

Can I Skip the Cereal?

For sure! If you’d rather just make a plain cinnamon cookie instead of the full Crumbl Cinnamon Cookie experience, feel free to leave off the frosting and/or Cinnamon Toast Crunch cereal topping.
